CLEANING APPARATUS.

To 0: whom it may concern:

Be it known that I, THOMAS H. Rrcrmno son, acitizen of the UnitedStates-of America, residing at Lexington, in the county of Davidson andState of North Carolina, have invented certain new and use fulImprovements in Cleaning Apparatus, of which the following is aspecification.

The primary object of the present inven' tion resides in the provisionof anovel form of steam producing devices for association with clotheswashing or cleaning .tanks with-the steam in passing to the tanks beingsuperheated for drying the samejand for obtaining the highest efficiencytherefrom, while a return pipe from the steam supply circuit returns thecondensation and waste steam to the boiler for reheating.

This application is a continuation in so far as disclosed in theapplication filed by Thomas H. Richardson on February 6, 1918, bearingSerial No. 215,628 and embodies improvements in the art thereover.

With the above and other objects in view, the invention consists in thenovel form,

combination and arrangement. of parts herein fully described and shownin the accompanying drawing wherein like reference characters indicatesimilar parts throughout the view which illustrates in side elevationand'partially insection a steam generator and cleaning tanks connectedthereto.

Referring more in detail to the accompanying drawing, there isillustrated a stand boiler 1 having a fillingpipe 2, a drain valve 3,water gage 4: and a steam gage 5, these parts being of ordinaryconstruction.

Steam generating means associated with the boiler 1 includes a gas tank6 having a hand pump 7 connected thereto for generating gas while a pipe8 extends from the tank 6 to the burner 9 beneath the boiler 1 forpurposes of heating the water therein. A heating device embodying adyeing vat, is arranged adjacent the boiler 1 and includes a casing 10supporting a dyeing vat 11 at its upper end and having the compartment10 into which a burner 12 is positioned said burner having a pipeconnection 13 with the gas tank 6. A pipe let extends from the bottom ofthe boiler into the casing chamber 10- and is looped as at 15 anddirected outwardly and upwardly of the casing as at 16 for entry intothe boiler as at 17, at a point above the water line as indicated. Thelooped portion 15 of the Specification of Letters Patent. Patented June15, 1920- Application filed November 28, 1919. Serial No. 341,193.

pipe being above the burner 12 will have the water therein heated to apoint for the generat on of steam which will. gather in the upper end ofthe boiler 1.

A steam supply pipe 18 is connected to the upper end of the boiler 1 andpasses through a casing 19 with the part within the casing coiled as at20 and valve controlled as at 21 at each side of the casing.

A burner 22 is positioned in the casing 19 beneath the coil 20 and has apipe connection 23 with the gas tank 6 for purposes of superheating thesteam contained within the coil 20. y

. A pair of cleaning tanks 24: and a drying tank 25 of similarconstruction are arranged upon the support for the boiler and heatingcase 10 and have the steam supply pipe 18 passing therethrough asindicated in the sectional view of one of the tanks 24:, that portion ofthe supply pipe 18 within the tank 24 being perforated as at v2.6 topermit the steam to escape therefrom and into the return of steam or.condensation, the hand and check valves 32 and 33 being positionedinwardly of the connections between the by-passes and the supply pipe.Thesupply pipe beyond the left hand tank 24 will be termed a return pipe34: which pipe extends through the heater casing 10 to be coiled as at35 and directly positioned above the burner 12, the return pipe 3 1projecting from the opposite side of the casing 10 and having a checkvalve 36 therein while the pipe extends upwardly into the boiler as at37 and terminates at a point above the water line therein.

From the above detailed description of the device, it is believed thatthe construction and operation will at once be apparent, it being 13 andthe steam generated therein escapes through the pipe 16 into the upperend of the boiler 1. Under control'or the valves 21, the steam escapingfrom the boiler 1 through the supply pipe 18 is superheated in thecasing 19 and is thence delivered through the supply pipe 18 to thecleaning 7 and drying vats 2d and respectively. Should it be desired todirect the flow of steam through all of the cleaning and dry- Y thecheck valve 36. Should it be desired to eliminate any of the cleaning ordrying vats,

the hand valves 31 in the by-passes may be regulated to control thedirectionoi flow of the steam, so that the desired vat or vats Vniay beused to the exclusion of others.

lVhile there is herein shown'and described the preferred embodiment ofthe invention, it is to be understood that minor changes may be madetherein without departing from 7 supply pipe and. the boiler, checkvalves in the spirit and scope of claimed: V
